Is NordVPN - a VPN proxy extension for Firefox safe?
NordVPN sends persistent device fingerprint and ISP metadata to its telemetry servers and loads feature-flag configuration from a remote CDN.
The extension collects a persistent device identifier along with OS, screen resolution, time zone, country, ISP name, and ISP ASN, and transmits these to applytics.nordvpn.com via its Moose telemetry library. Certain fields marked as essential are sent regardless of the user's consent selection. Additionally, the extension fetches a JSON configuration file from downloads.nordcdn.com that controls over 50 feature flags, including proxy domains and telemetry parameters, without subresource integrity verification.

Shared hosts - 10 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
